STAIR CUSHION Filed May 12, 1934 IN VEN TOR morrid Jaded BY 3 WHEY Patented Mar. 10, 1936 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to an improvement in stair cushions or stair coverings, and has for its object to provide a simple and inexpensive article of this character which will stand a great deal of wear under hard use and which will present a good appearance when in use.

One of the objections predominant in stair cushions and stair carpetings in use at the present time is the tendency of the covering or carpeting used in such cushions to separate from or pull out from under the metal re-enforcing binding usually employed about the edge of the cushion. The reason for this is that the carpeting is only secured by stitching near its edge under the metal re-enforcing strip or else is merely clamped under the strip. It therefore happens when frictional pressure of the feet against the carpet occurs, such pressure, after a short time, often breaks the stitching used for attaching the carpeting to its backing, or else slides the edge of the carpet from under the channelled re-enforcing strip so that the edge of the carpet becomes exposed and becomes frayed and the stair cushion soon presents an untidy appearance and must be replaced.

The primary object, therefore, of this invention is to provide a stair cushion or covering wherein these objections are obviated, and wherein a use of a padding between the carpet and the backing strip is dispensed with.

In the accompanying drawing wherein a preferred embodiment of the invention is disclosed, Fig. l is a perspective view of a stair cushion for riser and tread, made in accordance with the invention; Fig. 2 is a perspective view, with parts in section, showing the construction of the stair cushion; and Fig. 3 is a sectional view through the cushion.

40 The improved cushion is provided with a backing ID of a relatively rigid, though compressible, material such as a substantially thick and soft cardboard or the like. The covering H for this backing l0 consists of carpeting which has its 45 entire rear face l5 intimately united with the face of the backing ID by the use of a cement or adhesive l2. The backing and the carpet covering are of substantially similar size and shape and the entire marginal edges of both the 50 backing l0 and carpeting H are held together in a channel-shaped, metal, re-enforcing strip l3 which is provided with a plurality of holes l4 extending through it and through the edge of the carpeting and backing. These holes M are 65 adapted to receive fastening elements such as nails or screws 16 to secure the cushion in place on the tread and riser of a step in the positions substantially shown in Fig. 1. In Fig. 1 of the drawing, I have shown the two cushions usually employed, that shown at I! being adapted to 5 be placed on the tread of the step and that shown at 3 being adapted for the riser. Both cushions I1 and I8 are like in construction, their principal difference being that of size.

With the structure provided, the carpeting has 10 its whole area firmly attached to the backing and it cannot shift in regard thereto so that its edges cannot be pulled from under the re-enforcing strips I3. In this way, the carpeting is held perfectly fiat during the hardest possible con- 15 ditions of use, and wrinkling, crumpling, or distortion of the carpeted surface of the cushion is wholly prevented. As there can be no shifting of any portion of the carpet on the backing due to the adhesive attachment of the carpet there- 2() to, the edges of the carpet cannot move from under the re-enforcing strip so that the possibility of the edge of the carpet becoming exposed, and frayed and worn, is completely avoided. 25

The material selected for the backing I0 is preferably a relatively soft, compressible cardboard so that the cushion provides an essential softness and resilience so that use of padding between the carpeting and the backing member is avoided and the carpeting can be directly adhesively united over its entire area with the face of the backing.

What I claim is:

A stair cushion having a backing member composed of a single sheet of relatively stiff and nonflexible but compressible cardboard, a piece of carpeting conforming substantially in size to the backing member and having its entire rear face in intimate contact therewith and adhesively secured to the backing member whereby the backing member forms a cushioning as well as a stiff shaping element for the carpeting and any shifting movement of the carpeting relative to the backing member is prevented by the intimate attachment of the carpeting to said backing member, and a metal U-shaped reinforcing member extending completely around the edges of the strip and attached carpeting and covering and enclosing said edges, said member being provided with openings through which fastening members may pass to attach the cushion to a step.
